I don't think that's what he's saying at all, nor do I think it's an accurate statement. If the Vanguard can clear the map without the rest of the team, he's either extremely good, or he's high level and playing on Bronze, in which case he probably was doing it solely because he wanted an easy match.
His skill and/or desire for an easy match have nothing to do with what I said. It appears that I was wrong about what he was trying to say anyway, but I wanted to point that out.
Tyger Tyger, burning bright,
In the forests of the night;
What immortal hand or eye,
Could frame thy fearful symmetry?
